To all t0/1.0m it may concern.'

Be 1t known that I, IIAimYTUNsTALL, a subject ot George V, King ofEngland, and

a resident ot Fair Haven, in the county oi? Bristol and State otMassachusetts, have in` vented a new and` useful Improvement in CombingMachines, ot which the following is a specification. y In United StatesLetters Patent No. 1.351 076, issued to me, and No. 1,416,95L issued toJoseph Fessel, there are described certain improvements on the well.knownlleilman comber. In my Letters vPatent No. lLO'TG there are showntop combs each having a horizontal movement with mea-ns for moving ithorizontally. I have found after considerable study that the top combmounting and the adjustable means for operating the top comb may besimpliiied in various way, one oi which is below described.

p ll/lyinvention willbe understood by retorence to the drawings `inwhich it. is 'shown in its preferred form as applied to a double# sidedmachine like that of my said` patent. Figure l is an elevation partly insection ol so much ot a double headed machine ot the type shown in mysaid patent as relates to my present invention, this view correspondingsomewhat to Fig. 3 of my said patent and showing also a portion of themachine of the said F ossel patent.` y Fig. 2 is a plan thereof, themiddle portion ot one the heads being broken away, thus omitting thenipper frames, etc.

Fig. 3 is a sideelevation of the driving end of the mechanism.

Fig. 4 is a detail showing the adjustment ofthe top comb moving link.

` Figj is a detail taken at right angles `to Fig. 4;, showing also thetop comb an connection, and f Fig. 6 isa detailsimilar `to Fig. 4, ofthe top comb adjustment. 2

In these views certain of `the reference characters of the said patentsare used so that the location otmy present;improve` ment on the-originalmachine may be easily seen. In my said` patent the top combs wereoperated from the crank disklO on shaft 8 and, shafts 103. Inthepresentcase they areoperated bythe pendulum 12 whichrocks the shaft landtorthis purpose is forked as at 12a and is connected to a crank disk ,9on" shaft 8 by means substantially like thatshown in the said Fesselpatent, so

that the pendulum l2 and the shalt 13 may be given a lateralswinging oroseillating movement whichshall equal in point et time andextent in eachdirection.

The Fessel arrangement for swl pendulum l2 comprises a carriage tsleeves al ruiming on rods l havin block D2 iiith hole through 'it inwhich lies a crank pin l0. ln a housing Qnon crank lr r 9 is mounted ablock l0 through which .sl iis crank pin 'lO passes, and au adjusting'row lll passing through the outerwall oit the cranfl pendulu .1. Theforked end 19.@ oir thependuluin `l2 straddles a block e1` which ispivotally mounten in the car* l) so as `to turn slightly as requiredbythe swinging movementsv 'oi' the pendulum. lIhe rotation ot the crankdisk 9 causes the reciprocation ot the carriage I) and hence theswingingot the pendulum l2. i p Un the shaft I3 is mounted the plate llltastthereto, while the upper end of the pen dulum l2 is loose on the shaftI3 and is adH justably held in place with relation to thc shaft 'I3 and,plate llby screwslwhich pass through lugs in the plate land engage theedges of the pendulum l2 which are shaped for the purpose as lescrihedin said patents. i

'Ihe plate 14. is pr Yvided with a slot 141. and a bolt 121 projectstluough theslot lll-l and carries a nut by which the plate and pendulumare securely vfastenerfl together when the proper adjustment has beenmade by the screws l5.

In describing the operations of the top comb it will beunderstood thatin a doublesided machine as is shown in Fig. l .the parts are duplicatedon the two sides of the machine `and are operated in turn (as are thenipper trames) by the pendulum as it swings first in one direction andthen in the other. Ast-he parts are identical. a descrip tion ot theparts on one side only eta vertlcal line throught-he pendulum shaft I3will be necessary.

The pendulum shaft 13 carries a number of arms 36 each carrying a bowl37to operate the nipper trames as `shown in Fig. `l5 of my said patent.In my present invention 4- .ng die Y mounted in sup-v ports l2 on thetrame rl. Vertical ways D1. mounted on .said carriage `carry aV slidablethere are a series of bowls 37, as in my said patent.A On each rookableshaft 29 are carried arms 32 in line to be struck by these bowls. Tosecure uniformity of action in the case of a machine having a number oiheads, there may be a number of arms 3; and 36 located alongv themachine. say one or more for each head.

To the bottom of each arm 32 pivoted a link ,140 the outer end of whichis pivotally secured to an arm 141y mounted looselj-.f1 on the stubVshaft 142. Fast on the shaft 142 is a collar 143 carryino a plate 144having lugs 145 through which pass screws 146. these screws beine; inline with the edite of the arm 141 so that as an arm 141 is caused torock by the arm 32 and the link 140 the plate 144 will be moved becauseit is clamped to it by the screws 146, and will oscillate the shaft 142.The plate 144 is. provided with a slot 147 and a bolt 148 passes throughthe arm 141 and the slot 147 to clamp the plate 144 and Iarm 141together when their proper relationf'has been established in the primaryadjustment of the machine b v the screws 146. In 1 these scizews shownin 'clamping` position: in ll 4. the positionof these screws is shownprior to the preliminary adjustment of the machine.

On the stub shaft142 are also mounted arms 151,*one at each side of thehead. Between, each pair of arms 151 a top comb carrier 152 is mounted',the top comb 4S beiim` mounted between these carriers. There is aslotted adjustablev connection between the parts151 and1`52 to be usedin the primary adjustmentof the machine. Itwill be seen.v thatl thereciprocation of the links 140 will by thismeans cause the roc-king ofthesh'aft 142 andl hence the reciprocation the top comb carrier 152andthe top comb. and that as the rockable arms 141 are loose on theshafts 142. the throw of the top combunay be adjusted by adjustins theposition of the plates 144 about the shafts 142. The screw 149, which lpasses through the lujo 1 5() (see Fie'. 4), acts as .a safetydevice to,limit the movement of the system in case of any accident, for example,the breakage of the spring l323v which is shownA in mv said patent asholding together the arms- 32 thereof and whiclrcooperates with thescrews and stop 642 to limit their swine'. wWhere this mechanism is usedon a double-sided comber this 7arrangement is desirable because itutilizes but one springv to control the parts on both sides of themachine, I-'f the mechanism is 'used on a single-sided comber onel endof the spring' may be attached to theifriamc. the other end beingattached to the arm 32.

The frontv'endfofv each arm offthe top comb carrier 152 overhangrs thetop comb and rests upon a roller 153' which supports then so that theywill move in a horizontal line.

rllhe comb 48 is adjustablj" mounted at each end on an arm ofthe carrier152.y 'F or this purpose it is attached to links 155. one f each end,which are pivoted to these ai i at 154. The rear ends of these links areadjustably connected, by a slot and bolt connection. to the arms. 'lheseparts are -rfii so proportioneel that asin my said patent the top combwill have a proper relation with the fluted rolls 83 and 84 as indicatedin Fig. 1, and in view of the minuteness of the fibre and the necessityfor4 absolute accuracyv in the arrangement and movements of thr partsthe various adjustments above do scribed are found very desirable. Othermeans of adjustably connecting` the various parts may be adopted. if.-desired. but the above construction has been found in practice verysatisfactory. Such adjustment is, desirable to control the amount ofwaste removed andfor other purposes as will occur to those skilled inthe art,

It will be seen from the foregoingr description that my inventionrelates toa means ofy operating' a top comb and it is so claimed. lhileit is Shown as applied to the 'double comber of my patent, itisdoperable equilljY well in a single-sidedy comber having' means forrocking` the shaft 29 or otherwise yQivinslr the proper movementstotheparts referred to inthe claims in connection with means for git/ingto the arms 32 the necessariY swinging motion, which armsalso Operatethe iiipper mechanism as shown in my said Patent.

Itl will also be noted that as described in my said patent thesearms 32.and hence both the nipper frames and the top combs. havein fact a dwellwhilein their rearward position. that is. they swine back until thescrews 321 engagel the stop 642. these screws and stops serving toadjust the rearward position of the nipper frames and in this case thetop comb as well,v while allowing' the nipper frames and top comb'on theother side of the machine to perform their operations while therstuiamednippers and top comb are stationary. rllhe operation of the topcomb therefore from the arm 32. which causes in this case the swineineof the nippers, gives to these two parts a coordination in theirmovements which has been found extremely important.

That I claim as my invention is 1. In a machine of the kind describedhaving detaching rolls. a rockable shaft. a top comb frame and means forsupportingT said top comb frame'whereby it may be moved horizontally,and connections between said rockable shaft and said frame comprising arocker arm mounted on saidv rockable shaft and adjustable connectionsbetween said rocker arm and said frame whereby the throw of said framemay be adjusted and said.y frame willbe given an intermittent reingrolls.
